New Engine Mounts

Today I replaced the two engine/transmission mounts and dogbone mount. When I started the car it is noticably louder when idling. The louder idle happened after I replaced the dogbone mount. I started the car up after replacing the engine/transmission and the idle was the same as it was before. Overall, the car appears to be louder. Does it make sense that the car would be louder? Please let me know.

Make sure the engine is aligned correctly with mounts, there's a procedure to do this.
